Extract the files to a folder on your hard drive (right-click and select Extract All… from the pop-up menu). If you want to share the add-in with other users of the computer, make sure to put the files into a folder that all users can access.

Locate the files you unzipped in step 2 and select the version of the add-in you want (Basic Add-in: AnalyticsEdgeBasic-32bit.xll or AnalyticsEdgeBasic-64bit.xll; Standard Add-in: AnalyticsEdgeStandard-32bit.xll or AnalyticsEdgeStandard-64bit.xll ; Core Add-in: AnalyticsEdge-32bit.xll or AnalyticsEdge-64bit.xll ). NOTE: only one version will work depending on your installed Excel version (32-or-64 bit) — If one does not work, try the other.
